Have you notice when you are park on a up hill you will lose about 1 or 2 bars. If you park on a downhill you get a couple of extra bars assuming if your references was if the car was level before.

Do you mean the fuel indicator? If so, then yep, I get that. Mine varies +1 or -1 depending on the incline.

im guessing you mean gas. Most cars are like that. Its just that the gas isnt level, so the tank reads the level differently

the gas gauge in the dash is working because there is something floating in your gas tank, it reads how filled it is, when it is tilted, it will read the highest point, so it gives you a reading of more gas, this is why gas gauges are not completely accurate, you read more on it at www.howstuffworks.com and go under the auto section, you'll find it
